NVD Description
Note: Versions mentioned in the description apply only to the upstream libyang package and not the libyang package as distributed by Debian.
In function read_yin_container() in libyang <= v1.0.225, it doesn't check whether the value of retval->ext[r] is NULL. In some cases, it can be NULL, which leads to the operation of retval->ext[r]->flags that results in a crash.
